叶状柄

The cones are globose to ovoid, 1.5-2.5 cm in diameter with 16-28 scales, arranged in opposite pairs in four rows, each pair at right angles to the adjacent pair; they mature in about 8-9 months after pollination.

叶交互对生，在绿色脱落的侧生小枝上排成羽状二列，线形，柔软，几无柄，通常长1.3一2厘米，宽1.5一2毫米，上面中脉凹下，下面沿中脉两侧有4－8条气孔线，雌雄同株。

Leaves alternate; stipule sessile, usually ciliate, persistent; leaf blade palmately lobed or sometimes deeply dissected.

叶互生 托叶无柄，通常纤毛，持久；叶片掌状浅裂或有时深深的多裂。

Leaves alternate, solitary or in fascicles, petiolate to subsessile; leaf blade flat, linear-lanceolate to ovate, base cuneate, rounded, or subcordate, margin entire, apex obtuse or acute.

叶互生，单生或簇生，具叶柄到近无柄；叶片平，线状披针形的到卵形，基部楔形，圆形，或近心形，边缘全缘，先端钝或锐尖。

In the Filicinophyta, Sphenophyta, and Lyophyta the embryo sporophyte produces a footlike structure that remains embedded in the tissues of the parent gametophyte plant, absorbing nutrients like the suspensor of higher plants.

在真蕨门 filicinophyta ，楔叶门 sphenophyta，和石松门 lycophyta 中，胚胎孢子体产生足状结构，仍然包裹于双亲配子体植物内。胚胎吸收营养的方式同高等植物从胚柄那样吸收营养一样。

Areoles without glochids; leaves broad and flat, pinnately nerved,± persistent; flowers solitary or in inflorescences, mostly stalked; ovary superior to inferior; seeds black, not arillate.

没有钩毛的小窠；叶宽和平，成羽状叶脉，多少宿存；在花序，多数柄里的花单生或；子房上位到下位；种子黑色，不具假种皮。 1 Pereskia 木麒麟属

Cauline leaves shortly petiolate or sessile, not auriculate, entire or pinnatisect.

Plants not pulvinate,(5-)8-25(-30) cm tall; petals (3-)3.5-5 mm; leaf trichomes narrowly lanceolate in outline, with only 2 principal minute branches from stalk apex; seeds (1.8-)2-2.5 × 1-1.5 mm

垫状的不植株，(5-)8-25(-30)厘米高；花瓣(3-)3.5-5毫米；狭披针形的叶毛状体轮廓，概括地2 主要小分枝从柄先端那里；种子( 1.8-)2-2.5 * 1-1.5 毫米 10 A。

Cauline leaves petiolate or sessile and cuneate or auriculate, pinnately or palmately veined, entire, dentate, or crenate; ultimate veins ending or not with apiculate callosities.

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
